Essential System Tools: GreenWithEnvy – NVIDIA graphics card utility

Last Updated on March 16, 2023

This series highlights essential system tools. These are small utilities, useful for system administrators as well as regular users of Linux based systems. The series examines both graphical and text based open source utilities. For details of all tools in this series, please check the table in the summary section.

GreenWithEnvy (GWE) is a graphical system tool for NVIDIA graphics cards. This utility provides information about the card present in a system together with the ability to control its fans and overclock the GPU and memory.

GWE is free and open source software.


We tested the software on a fresh installation of Ubuntu 22.04. The developer recommends installing the utility from Flathub. Installation was plain-sailing all the way.

On our fresh Ubuntu, we first need to install Flatpak. Issue the command:

$ sudo apt install flatpak

Next, add the Flathub remote repository to our flatpak repository configuration.

$ flatpak --user remote-add --if-not-exists flathub

We can now install the software with the commands:

$ flatpak --user install flathub com.leinardi.gwe
$ flatpak update # this command wasn’t necessary on our Ubuntu 22.04 system.

Run the utility with the command:

$ flatpak run com.leinardi.gwe

The software is then added to Activities.

We also need to enable the overclocking and fan control functionality as they are not enabled by GWE itself. Note that overclocking can permanently damage your hardware if the system doesn’t have sufficient cooling. Overclocking is controlled via the Coolbits option in the Device section of Xorg.

The utility provides some general statistics including model name, driver version, gpu/memory/power usage, temperature and fan(s) speed.

What makes GWE so useful is that it gives you control of the graphics card. We can overclock the GPU and memory. We can also alter the power limit. This is helpful if you want to squeeze out more performance or even reduce your energy consumption. With our Asus GeForce RTX 3060 Ti OC Edition the minimum power draw is 100W.

The ASUS card we’re using provides a stop mode which halts both fans when the GPU temperature falls to 50 degrees C. But not all 3060 Ti’s provide this stop mode. And many other NVIDIA cards also lack this functionality. That’s when GWE steps in as it lets you define your own custom fan curve profiles.


If you come from a Windows background you’ll know there are a wide range of utilities that let you fully control NVIDIA cards.

GWE is an essential utility for Linux NVIDIA graphics card users given that tools such as MSI Afterburner and GPU Tweak II are Windows-only. While GWE only provides some of the tweaking possibilities that MSI Afterburner or GPU Tweak II offer, there’s enough functionality here for most users. It’s a worthy addition to our Essential System Utilities series.

The maintainer of GWE has stated that he may no longer be able to support this utility in the future. If you want to contribute to open source software and have a good knowledge of Python 3, take a look at the source code! If the developer does decide to step away, we’d love to see the project continue. At least that’s a possibility given the project is open source.

NVIDIA released open-source Linux GPU kernel modules in May 2022. Maybe NVIDIA could take the next step and either port GPU Tweak II to Linux, or contribute to GWE?
